dated December 1 1, 1894.

Application filed April 23,1894. Serial No. 508,633. (No model.)

To aZZ whom it, may concern:

Be it known that we, SAMUEL F. GREENE and SETH W. LAW, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Window-Shutters', of which the following is a full, tion.

Our invention relates to improvements in window blind shutters, and has particular reference to that class of such devices in which the shutters are formed of a solid portion and a slatted portion, the slats being adapted to be opened and closed, to admit light, &c.

The object of our invention is to provide a blind in which when the slats are closedno light Will be admitted, one slat overlapping the lower edge of the slat above it. A further object is to provide a bead for the slats which is capable Aof easy removal from the shutter, the purpose being to furnish a ready means whereby a slat can be readily removed from the slatted portion, without the removal of the entire shutter from its hinges, should a slat be broken or defaced, and also to enable the shutter to be more easily renovated and painted, by reason of the fact that by removing the slatted and the slatted portion can be worked on to A further object is to provide a shutter which will be neat in appearance, simple in operation and durable in construction.

With these objects in view, our invention consists in the improved construction and combination of parts as more particularly described and pointed out in the claims.

In the drawings:-Figure lis a horizontal section of the slatted portion of a window shutter, showing the slats in their open position. Fig. 2* is a similar view, showing the slats closed. Fig. 3 is a detail perspective sectional view, showing the slats open in full lines, and closed in dotted lines. Fig. 4.- is a vertical section of the slatted portion, the slats being omitted, to showone form of bead securing device. Fig. 5- is a similar view, showing another vice'. Fig. 6- is button, used in an edge view of the spring connection withthe form clear, and exact speciticaf' portion, both the solid portion form of bead securing de- Yshown in Fig. 4; and Fig. spec-tive view of one end of the bead.

`Similar numerals of reference indicate similar parts in all of thetgures of the drawings. Referring to the drawings, l designates a 'portion of thel frame of a shutter, inclosing the slatted portion.

2 indicates the bead by means of which the slats are secured in place. 3 designates slats, `formed as best shown in Fig. 3, in which the edges are enlarged as at 4, extending from opposite sides.

5 designates longitudinal ribs located on opposite sides ot' the slats for the purpose'of Vstraightening them, and/also to keep them from warping. These slats are formed without .trunnions, their ends presenting an even surface` and thereby capable of more easy v manufacture.

The bead 2, is formed of sheet metal, having its end bent at an angle, by which an open- `ing is 'formed between the bead and the frame `ofthe shutter, as shown in Figs. 1 and 2. The beads have openings 6, placed at suitable intervals of its length, by means of which the 'screws or tacks 7, pass therethrough, and -passing into one edge 4 of the slat 3, the screw `or tack forming the trunnion on which the slat revolves.

Secured to the opposite edge of the slats i from the one connected to the bead, is a metal strip 8, having one edge rounded, as at 9, for a purpose hereinafter specified, which is adapted to securely hold the slats in their relative positions. 1

Referring to the means for-.securing the -bead in place l0 designates an opening in the lower frame of the-slatted portion, of suiiicient depth to keep the rounded portion 11, of thebead 2, formed by making a kerf 0n each edge of the bead, a sufficient depth t0- ward its center and then turning the edges toward each other and thus forming a cylindrical portion, in position, when placed thereip. This means of securing the lower end of the bead is to be used in both forms of the securing device.

In the form shown in Fig. 4, 12 designates a spring bottom, which is adapted to be secured to the bead 2, near its upper end, the

upper end of the button, extending above the enlargements Y IOO the end of the bead 2, the same distance as the length ot the rounded portion 11. This spring button consists of a strip of spring metal bent, at about its center, at an angle greater than a right angle, as shown at 13, in order that, when the bead is to be inserted, and the spring is to be turned into position, the tendency of the spring will be to push against the top frame of the slatted portion, and thereby hold the bead in position.

Referring to Fig. 5, the bead 2, has formed at its upper end, a rounded portion 14, formed in the same manner as the rounded portion 11 at the lower end ofthe bead. This rounded portion is adapted to be inserted into an opening 15, in the top frame of the shutter, ofy

greater depth than thelength of the rounded portion 14. Secured around the rounded portion 14 is a rubber washer, 16, by means of which the lower end of the bead is held in position in the opening 11. XVe do not limit ourselves to the use of a rubber washer, but may use a spiral spring, orany other yielding device for the same purpose.

From the above description, the operation will be as followsz--Vhen it is desired to secure the slatted portion into the shutter, by means of the device shown in Fig. 4, after the slats have been placed in position on the bead, bymeans of the openings 6 and screws or tacks 7, the lower end of the beads (one on each side of the slats), are inserted into the openings 10, the beads pushed into vertical position, and the spring buttons pushed upward into position, the spring of the horizontal portion, holding the beads in position. Should one of the slats become broken, the slatted portion is removed from the shutter by reversing the above operation and the screws or tacks 7 removed, and the slat will drop out. A new slat is inserted and the slatted portion secured in position.

When the form shown in Fig. 5 is used, after the slats have been fastened in position, the rounded portion 14 of the beads is first inserted in opening 15, the rubber washer having iirst been placed on the rounded portion. The slats and beads are then pressed up into the opening a sufficient distance to allow the lower rounded portion of the bead to enter the openings 10, when by leaving the slatted portion drop the rounded portion will fall into position in the openings 10, and the rubber washer will serve to keep it from jumping out, in ordinary usage. By reversing the above operation the entire slatted portion may be removed for painting, or other purposes.

As seen in Fig. 3, the form of the slats is such, that when they are open a maximum amount of light can enter between them, but when they are closed, as shown in dotted line in said figurano Ilight can enter between the slats, owing to the fact that one enlargement fits over the enlargement of the next slat above, and consequently prevents the admission of light. i

The rounded portion 9 of the metal strip, is for the purpose of holding the slats in position when open or closed, and also, when the slats are closed, to prevent the light entering through the openings left between the ends of the slats and the bead, the edge of the rounded part fitting against the face of the frame, as best seen in Fig. 2.

Minor changes in construction, die., may be made without altering the rights and advantages of our invention.

Having thus described our invention, what we claim as new, isn

The combination with the frame l, having openings l0 in the lower portion;`ot the beads 2, the rounded portion 11 ot which is adapted to tit in said openings 10; slats 3 having enlarged edges 4 and longitudinal ribs 5, secured to said beads by means of screws or tacks 7 passing through openings 6 in said beads, the said bearing points being located at the center of the enlargements 4 of the slats 3; the metallic strip' 8, having rounded edge 9, secured to the ends of the slats opposite to the bearing point ot means for removably securing the upper ends of said beads to the upper portion of the frame, substantially as described.

In testimony whereof we have hereunto set our hands this 19th day of April, 1894.
